1. What is Vertical Reaction at Bearing 2?

Vertical Reaction at Bearing 2 due to Crankpin is the vertical reaction force acting on the 2nd bearing of the crankshaft because of the force acting onto the crankpin. This calculation is essential for analyzing load distribution and structural integrity in crankshaft design.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ R_{v2} = \frac{P_p \times b}{c} \]

Where:

\( R_{v2} \) — Vertical Reaction at Bearing 2 (N)
\( P_p \) — Force on Crank Pin (N)
\( b \) — Overhang Distance of Piston Force from Bearing1 (m)
\( c \) — Distance Between Bearing1&2 of Side Crankshaft (m)

Explanation: This formula calculates the vertical reaction force at the second bearing based on the principle of moments, considering the force applied at the crankpin and the distances between bearings.

3. Importance of Vertical Reaction Calculation

Details: Accurate calculation of bearing reactions is crucial for proper crankshaft design, bearing selection, and ensuring the structural integrity of the engine assembly under operational loads.

4. Using the Calculator

Tips: Enter force on crank pin in Newtons, overhang distance in meters, and distance between bearings in meters. All values must be positive and non-zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: Why is this calculation important for crankshaft design?
A: This calculation helps determine the load distribution on bearings, which is essential for selecting appropriate bearings and ensuring the crankshaft can withstand operational forces.

Q2: What factors affect the vertical reaction at bearing 2?
A: The reaction force depends on the magnitude of the crankpin force and the geometric configuration (distances b and c) of the crankshaft assembly.

Q3: When is this calculation typically performed?
A: This calculation is performed during the design phase of engine development and when analyzing crankshaft performance under different loading conditions.

Q4: Are there limitations to this formula?
A: This formula provides a simplified static analysis and may need to be combined with dynamic analysis for complete crankshaft design evaluation.

Q5: How does this relate to other bearing reactions in the system?
A: The vertical reaction at bearing 2 is part of a system of equations that must satisfy equilibrium conditions for the complete crankshaft assembly.
